We study the decay width and CP asymmetry of the inclusive process b --> sgg (g denotes gluon) in the three and two Higgs doublet models with complex Yukawa couplings. We analyze the dependencies of the differential decay width and CP asymmetry to the s-quark energy E-s and CP violating parameter theta. We observe that there exist a considerable enhancement in the decay width and CP asymmetry is at the order of 10(-2). Further, it is possible to predict the sign of C-7(eff) using the CP asymmetry.

The exclusive B -> (K, K*)l(+)l(-) decays in a CP softly broken two Higgs doublet model
Erkol, G; Turan, Gürsevil (2002-07-22)
We study the differential branching ratio, forward-backward asymmetry, CP-violating asymmetry, CP-violating asymmetry in the forward-backward asymmetry and polarization asymmetries in the B --> Kl(+)l(-) and B --> K*l(+)l(-) decays in the context of a CP softly broken two Higgs doublet model. We analyze the dependencies of these observables on the model parameters by paying a special attention to the effects of neutral Higgs boson (NHB) exchanges and possible CP-violating effects. We find that NHB effects a...
The exclusive B-s ->phi l(+)l(-) decay in the two Higgs doublet models
Erkol, G; Turan, Gürsevil (2002-11-01)
We study the differential branching ratio, the branching ratio and the forward-backward asymmetry for exclusive B-s --> phil(+)l(-) decay in the two Higgs doublet model. We analyze the dependences of these quantities on the model parameters and show that these observables are highly sensitive to new physics and hence may provide a powerful probe of the SM and beyond.
The exclusive B ->pi l(+)l(-) and B ->rho l(+)l(-) decays in the general two Higgs doublet model
Erkol, G; Turan, Gürsevil (2002-02-01)
We study the differential branching ratio, branching ratio and the forward-backward asymmetry for the exclusive B --> pil(+)l(-) and B --> rhol(+)l(-) decays in the general two Higgs doublet model including the neutral Higgs boson erects. We analyze the dependencies of these quantities on the neutral Higgs boson contributions and the other model parameters. We observe that two Higgs doublet model with the neutral Higgs boson exchanges gives quite sizable contributions to these observables for both channels ...
The mu -> e gamma and tau ->mu gamma decays in the general two Higgs doublet model with the inclusion of one universal extra dimension
Iltan, EO (2004-02-01)
We study the effect of one universal extra dimension on the branching ratios of the lepton flavor violating processes mu --> egamma and tau --> mugamma in the general two Higgs doublet model. We observe that these new effects are tiny for the small values of the compactification radius R. Furthermore, we see that these effects are comparable with the branching ratio obtained without including extra dimension, if the neutral Higgs bosons are nearly degenerate and the complexity of the Yukawa coupling, induci...
The aniıhilation cross section of the dark matter which ıs driven by scalar unparticle
Iltan, E. O. (2013-08-01)
We analyze the annihilation cross section of the Dark Matter which interacts with the Standard Model sector over the scalar unparticle propagator. We observe that the annihilation cross section of the dark matter pair is sensitive to the dark matter mass and the scaling dimension of scalar unparticle. We estimate a range for the dark matter mass and the scaling dimension of scalar unparticle by using the current dark matter abundance.
